2010 197 missfire

[Cheg]

I've got a 197 with a bad miss fire!
plugged the computer in, no faults. Checked plugs, fine. Checked each coil, they're fine. Compression test, was down one 1 and 2. Pulled head off, lapped valves in 1 and 2 in, built back up, still missing! Replaced coil and injector loom, still missing with no faults!

any ideas?

Will be either pencil coil or plugs. I had the same

I've had new plugs a few weeks back. I've swopped coils over off another Clio. Still misfired with coils swopped over.

Anyone else have a solution to this as mine has started to do the same?

 

[Yiannis197]

Is there a chance to be the injectors possibly?

you need to check it out correctly/proper diagnosis than assuming its the same as someone elses fault.....
